A Right-angled Trapezium
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.

right angled triangle
a house shape: a floor, 2 parallel walls and an angled roof
A shape with three sides is called a triangle: 3 equal sides = equilateral 2 sides same length = isosceles 1 right angle = right-angled triangle
see if the shape has four sides if they have you have found the square Check if all 4 sides are of the same length and if the interior angles are all 90° (right angled)
The shape of 2D is a flat surface.
A rectangle is a shape with four sides, and four right-angled corners.A square is with four sides of equal length, and four right-angled corners.Since the rectangle doesn't have any rules regarding the length of the sides, all sides could be the same length, and it would still be a shape with for sides, and four right-angled corners. Answer: The set of all shapes meeting the criteria for "Squares" is included in, but not convergent with, the set of all shapes meeting the criteria for "Rectangles"
A pentagon has 5 sides. A hexagon has 6 sides. The penta- prefix comes from the Greek for 5; The hexa- prefix comes from the Greek for 6. The -gon suffix comes from the Greek for "corner" or "angle". Thus a pentagon is a five cornered (or five angled) shape; and a hexagon is a six cornered (or six angled) shape.
right angled triangle does not have all equal sides
